A
  • restorations that completely absorb x-rays; as a result, little to no radiation contacts the receptor (appears radiopaque)
  • (ex: amalgam, gold)

70
Define the term: edentulous patient
a patient without teeth
71
Define the term: radiopacity / radiodensity
an area on a dental image appearing radiopaque *(light/white)* due to resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the image receptor
